When you order your belts you have a few decisions to make. The most critical is the mounting configuration. If you have a full rollcage or at least a harness bar, you can use the wraparound-style mounting. Your other option is to go with a bolt-in mount, where you will have to purchase mounting tabs to web your belts through. These tabs can then be used to bolt your belts into your car. The second decision you'll have to make about your belt purchase is how you want your belt adjustment to work. You can have your belts adjust by pulling up or down on the belt tabs. The belt adjustment is a matter of personal preference, but some applications and seat designs work better with one adjustment style over another.
